For RTP3000S and RTP3000D systems:
Configure ipaddress and ipaddress_b. Note! It is recommended to configure ipaddress
and ipaddress_b to be on different networks.
Note!
For RTP3000S system, use PTDBM application and configure node as Single and
define IP Address and IP Address2 for redundant host communication.
For RTP3000T systems:
Configure ipaddress for node processor A, ipaddress_b for node processor B and
ipaddress_c for node processor C.
For RTP3000Q systems:
Configure ipaddress for node processor A, ipaddress_b for node processor B, ipaddress_c
for node processor C and ipaddress_d for node processor D.
If the IP address parameter for a node processor is not configured, and this node processor is
inserted into the RTP3000 system, then the following display status message will be printed:
Node Processor %s – Requires Configuration File IPAddress
where %s is the newly inserted new node processor B, C or D, which is not configured in the
configuration file. Likewise, if the user application program has less node processors configured
than what is physically configured then the following display status message will be generated:
Node Processor %s – Requires I/O Configuration Node Update
where %s is the newly inserted new node processor B, C or D, which is not configured in the
NetArrays user application program file’s IOC page.
Subnetmask
The subnetmask parameter specifies the subnet mask to the processor card. The format of the
subnet mask is
nnn.nnn.nnn.nnn
, where
nnn
can be any number from 0 to 255 (Default value is
255.0.0.0, which is suitable for an internal or private network).
Scan cycle
If the configuration file is deleted, the default scan_cycle entry is set to 250, which equates a fixed
scan rate of 25 milliseconds or 40 passes per second. For RTP3000S, RTP3000D, RTP3000T
and RTP3000Q systems, this parameter may be changed to a scan_cycle of
50, for a fixed scan rate of 5 milliseconds or 200 passes per second or
100, for a fixed scan rate of 10 milliseconds or 100 passes per second or
150, for a fixed scan rate of 15 milliseconds or 67 passes per second or
200, for a fixed scan rate of 20 milliseconds or 50 passes per second or
250, for a fixed scan rate of 25 milliseconds or 40 passes per second.
Nodenum
A node number is required for Peer-to-Peer communications in a multiple-node configuration.
Node numbers can range from 0 to 99. Each peer node must have a unique node number from 1
to 99. A node number of 0 (zero) disables Peer-to-Peer communications for the node (Default
value is 0). The assigned node numbers are then used for the creation of peer variables in the
NetArrays project program.
Maxconn
The maxconn parameter specifies the maximum number of TCP/IP network connections (sockets)
allowed. The maximum value is 215 (Default value is 50).
For example, each host that connects to this node consumes one connection, each peer node that
receives data from this node consumes one connection, and each peer node that sends data to
this node consumes one connection. The total number of all these connections must not exceed
the value entered for this parameter.
